UNITED STATES PATENT OFFICE. ELOF I-I. MEDEN, OF PHILAIlElLPI-IIAZENNSNLVANIA. ASSIGNOR TO AMERICAN GAS- ACCUMULATOR COMPANY, OF PHILADELPHIA. PENNSYLVANIA, A CORPORATION OF NEWV JERSEY.

To all whom it may concern:

Be it known that. I, ELor H. M'noiix, a subject of the King of Sweden, residing in the city of Philadelphia, county of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in Marine Lanterns, of which the following is a specification.

. One of the objects of my invention is to provide a. lantern with novel means for insulating or separating the fresh cool air entering the lantern from the gases of combustion and other heated gases which are escaping from thelantern so that a maximum diiference of temperature between the two, which is essential to the proper function of the lantern, may be maintained.

A further object of my invention is to provide an opening for the escape of any water which may find its way into the interior of the lantern with novel means for preventing the water from entering through said opening into the interior of the lantern, and also for preventing a strong or undue draft of air said opening into or through said lantern.

A still further object of my invention is to provide novel means whereby access to the lamp or light flashing apparatus within the lantern may be facilitated and whereby also the interior of the lantern may be made more readily'accessible for the purpose of being cleaned. 1

Other objects and advantages of my invention will be referred to in the detailed description thereof which follows or will be apparent therefrom.

In order that my invention may be more readily and clearly understood reference should be .had to the accompanying drawing forming a part of this specifi ation and in which,

Figure 1 is a central longitudinal sectional view. of a lantern embodying my invention; and Fig. 2 is a transverse section thereof on the line of Fig. 1. Y

Referring to the drawings, 1 designates the base of a lantern provided with projec- .tions 2 (one of which is shown) by means of which it may be secured to any suitable support. The flash light apparatus 3 or other suitable lighting means is supported upon the base 1 interiorly of the lantern. The lantern lens 4 is supported upon an inwardly extending lateral flange 5 which is Specification of Letters Patent.

provided at the upper edge of an annular member 6 which is adapted to overlap, as indicated at 7, the upper edge of the base part 1. The annular member 6 is hingedly connected at 8 to thebase 1 and is adapted to be held in closed position as shown in Fig. 1 by means of the screw-threaded headed bolt 10, Intcrposed between the flange 5 and the lower end of the lens 4: is

a washen, 11. A packing 12 is interposed between the outer lower edge portion of the said lens and the inner upper edge portion above the flange 5 of the annular member 6.

15 designates a tubular transparent member which may be designated as a chimney which surrounds and protects tne light of the lighting apparatus 3. The said chimney is supported upon supporting brackets 16 (one only of which is shown) which are secured to the under side of projections 17 extending inwardly from the flange In addition to the top of the lantern comprising the spaced cap-like portions 20 and 21 the hood of the lantern comprises a truncated cone-shaped member 22 and a corresponding member 23 spaced therefrom. The member 22'is secured at its upper end to the upper end of the conduit Qct which conveys hot combustion and other gases from the interior of the lantern. The gases escaping from the conduit 24c pass over the upper edge of the same, through perforations in the skirt of the member 20, then over the upper edge of the member 22 and out under the lower edge of the member 21. Said member 22 is secured at its lower edge by means of rivets 25 to the upper part of the outwardly and downwardly inclined skirt-like portion 26 of the annular outwardly and upwardly flared member 27. The latter member extends around and is secured to the upper end portion of the annular member 30 which may be described generally as of inverted truncated coneshape. In fact the two members 27 and 80 taken together may be so described. The lower edge of the said member 30 is in contact ,with and extends around the conduit 24 situated centrally of the upper portion of the lantern. The nduit 24 is provided with a bead 32' formed by pressing a ring of the metal thereof outwardly against which the lower edge of the member 30 contacts. The joint between the lower end of the member 30 and the conduit 2%; also s end of the annular member 40 and its lower edge is bent inwardly around the lower edge edge of the said member 23-; also that the '15.

the connection between the lower end portion of the member 22 and the depending skirt part 26; and also the connection between the upper end of the said member 22 and the upper end of the conduit should be air-tight or nearly so so that the entry or air or gases into the space betweenthe members 22, 27, and 24 is prevented.

It will be observed that the lower edge of the member 21 while it is spaced from the upper edgeof the member 23 overlaps and extends below it and thereby tendsto prevent the passage of water over the u per member, 23' is provided with a bafl'leplate or flange'31 which tends to prevent the entry of water through the space between. the

lower edge portion of the member .21 and the upper edge portion of the member 23.

I F or the purpose of preventing as far as possible the passage of water through the openings (provided for theentry of fresh cool air into the interior of the lantern) and upwardly through the annular space be"- tween the members 22 and 23 the lower end of the member 22 is extended beyond its line of connection with the skirt 26 as shown at 35. a .upon a flange 42 which-extends laterally neathside of'the flangef12.

extended inwardlyfas indicated at 62. The

upperside ofthe said inwardly extended portionis beveled downwardly, as indicated at 63. *Ilhave also provided the said-open ing with a bathe construction which consists of annular plate-like. meinbers65which are I supported attheir outer edges, one upon the other, upon a shoulder 66 formed in the bottom ofthe base 1,; which members extend inwardly and downwardly within the said opening 60. These annular members 65 are secured in position by means of screws 67- which extend through theirrouter'edges and engage tapped openings in said shoulder.

These screws alsoextend through the outer edge of and-secure in me 1nber 68 which rests upon the uppermost of the annular -members 65. v

a 73 designatesthin annular and downwardly' extending members which alternate with the inner edges of the annular members'65. These annular members are spaced from eachother by means of sleeves 75 which are supported upon abolt 76 which binds thesaid annular'menibers'73 together and also to the center of the It is apparent that'for either water or-airto enter. the lantern through the ope11 ing 60 it would be necessary for the same-to travel a zigzagcourse around the overlying and overlapping-edgesof the flange 62 and the annular members 65 and 73. The mean-s just described for partially closing the opening 60 permits access of air to the interior of the lantern so as to efficiently ventilate the same but prevents the same from jblowin gspider-like mem through the said opening with sufficient" force or with suflicient draft to cause the I extinguishment of the light. Itis apparent that by reason 'of the presence of theannular triangular space between the members 22, 27, 30 and the tubular conduit 24L .thc cool or cold air from the outside is prevented from contacting with the said conduit to cool the same. 'By this arrangen I I position a spider-like ment the temperature. of the air as it travels toward the burner of the lamp or flash light apparatus 3 is maintained at the lowest possible temperature while the temperatures of the escaping gases of combustion and heated air are maintained at as high a temperature as possible under the conditions of opera tion. These relative conditions of temperature are essential requirements for insuring strong and proper draft and circulation of air through the lantern. The space between the members 22 and 23 is open at both the upperand lowenends so as to equalize the wind" "ressure and thereby prevent a draft into h e lantern to extinguish the light.

It is also apparent that when the securing or fastening bolt 10 is removed all of the upper portion of the lantern, including the annular member 6 and all of the parts supported thereon and thereby, may be turned upon the hinge 8 so as to completely expose the lighting apparatus 3 to thereby render the same easily accessible for the purpose of repair or for any other purpose. Such construction and arrangement also enables ready and easy access to the interior of the lens whereby it may be easily and readily cleaned. p
